CURTAIN-POLE AND SOCKET.

SPECIFICATION forming part of Letters Patent No. 632,420,dated September 5, 1899.

Application filed January 21, 1898. Serial No. 667,409- (No model.)

To all who/1t it TIL/LL concern.-

Be it known that 1, JAMES \V. LESLIE, of Melrose, county of Middlesex, State of Massachusetts, have invented an Improvement in Curtain-Poles and Sockets, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates more particularly to poles for suspending heavy curtains or portieres; and one of the objects of my invention is to provide a curtain-pole of handsome appearance and simple construction upon which the rings attached to the curtain or portiere may travel with a minimum of friction and with the least possible tendency to bind or cramp when the curtain is drawn.

Another object of my invention is to construct a curtain-pole with which plain rings may be used without twisting and with but little friction.

Another object of my invention is to provide a pole which will effectually conceal the cords or wires employed to traverse the rings upon the pole.

Another object of my invention is to provide means for securely looking the metallic envelop upon the core of wood or other suit able non-metallic material.

Another object of my invention is to provide a novel socket which permits the ready erection or withdrawal of the pole when nec essary.

Other 'objects of my invention are such as proceed from the construction and arrangement hereinafter described in the specification.

Figure 1, in side elevation and centrally broken out, represents a doorway or window frame provided with a pole and socket embodying my invention. Fig. 2 is a perspective detail, enlarged, of a section of pole with the movable member of the socket thereon. Fig. 3 is a perspective view of the cooperating fixed member of the socket. Fig. 4 is an enlarged cross-section of the pole on the line :0 :r, Fig. 1, with a ring in place. 7 Fig. 5 is an enlarged section on the line as as, Fig. 1, look.. ing toward the right; and Figs. 6 and 7 are perspective views of the end of a pole with single and double traverse devices, respectively.

l have herein shown the curtain-pole as comprising a core a, of wood or other suitable material, covered by a metallic envelop I), such as sheet-brass, the envelop being bent along the top of the pole to form two parallel longitudinal ridges Z) 1), narrow at their upper edges and providing tracks upon which the rings R travel, the narrow ridges presenting a minimum of friction and at the same time supporting each ring at two points, steadying the ring and enabling it to travel freely without undue swaying or cramping. The rings are provided with suitable eyes R, to which the curtain or portiere C, Fig. 1, is attached in any desired manner. By applying a very small quantity of oil to the ridges b the friction is still further reduced. The two longitudinal edges 6 of the envelop are brought together between the ridges and bent over, as at b Figs. 4.- and 5, and forced into the material of the core to form a lock, the bent-over parts Z1 diverging as they are driven into the core to thus more securely lock the envelop in place. The comparatively narrow strip of the envelop between each edge b and the ridge 7) serves also to assist in looking the en velop, the ridges acting as abutments to withstand any tendency to accidentally withdraw the locking lips or bends b from the core.

In the construction of pole herein shown the core a has a longitudinal trough or groove a therein at its top and preferably having concaved sides, the ridges Z) of the envelop being located at the edges of the groove (1. It will be noticed that the part b of the envelop is concaved to rest snugly against the bottom and side of the groove, and this concavity of the envelop still further serves to strengthen the lock and prevent withdrawal of the locking-lips If. The envelop is applied to the core in any suitable manner to closely embrace and correspond to the contour of the core.

It is desirable to have a convenient socket for holding the pole in place, and I have herein shown a very convenient device well adapted to the purpose.

In Fig. 3 I have shown what I term the fixed member of the socket, consisting of a metal base 61, having openings cZ (see dotted lines) for attaching screws, as 5, Fig. 5, to hold it securely against the door or window frame, as in Fig. 1, said base being provided with a segmental flange d, extended at right angles thereto and adapted to embrace the upper part of the pole when the latter is in place. Slots (Z are made in the flange to receive the ridges b of the form of pole herein described, and the engagement of the flange with the ridges prevents rotation of the pole. The movable member of the socket is shown in Fig. 2 as a ring (1 loosely embracing and movable upon the pole, and herein said ring is provided with a locking-slot d, to be entered by a projection 61 on the segmental flange of the fixed member. To set the pole, the member 61 is slipped back from the end ofthe pole and the latter is lifted and passed up from below into the flange d, after which the member (Z is slid forward to cause the projection 61 to enter the slot 01 and a partial turn of the ring (1 locks the two parts of the sockettogether. It will be obvious that when so locked the member d supports the pole, and said member in turn embraces and is supported by the flange cl of the fixed member of the socket. One or both sockets may be made as described, and it will be noticed that the pole can be cut to exactly fit between the bases of the two fixed socket members, so that there will be no longitudinal movement or play of the pole.

The groove in the top of the pole effectually conceals any traverse cords or wires when used, and still to the eye the pole has the appearance of a cylindrical bar or rod.

In Fig. 6 a pulley-plate f is shown attached to the end of the pole and bent over to form ears f for a pulley f for the traverse-cord, the ears and pulley being concealed in the groove in the top of the pole.

A double-pulley plate g is shown in Fig. 7, having in this instance outwardly-turned ears g for the pulleys g g which extend be yond the end of the pole, and with these de-- vices, particularly the one shown in Fig. 7, the segmental socket-flange is made deeper than shown in Fig. 3 to receive and conceal the pulleys and cords.

The ring or collar (i forming a movable socket member, is preferably cut away, as at d, (see dotted lines, Fig. 2,) to permit the cords to pass freely downward out of the socket if traverse-cords be used.

By the use of my socket the pole, with rings and curtain, can be removed instantly after unlocking and slipping back onto the pole the movable socket members, and when the pole is in place all of the traverse-cords and pulleys are concealed from view.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A curtain-pole comprising a core, and a metallic envelop therefor having parallel longitudinal ridges on its top, projecting beyond the main surface of the envelop, the longitudinal edges of the envelop being brought together and bent over and forced into the material of the core between the said ridges, to form a lock for the envelop.

2. A curtain-pole comprising a core, and a metallic envelop therefor having parallel longitudinal ridges on its top, extending outwardly beyond the main surface of the envelop, the longitudinal edges of the envelop being brought together and bent over and forced into the material in divergent directions between the ridges, to form a lock.

3. A curtain-pole comprising a core having a longitudinal groove in its top, and a metallic envelop having parallel longitudinal ridges along the edges of the groove and projecting beyond the periphery of the core, the longitudinal edges of the envelop being brought together and bent over and forced into the bottom of the groove between the ridges to form a lock.

at. A curtain-pole comprising a core having a longitudinal groove provided with concave sides in its top, and a metallic envelop having parallel longitudinal ridges along the edges of the groove, the adjacent longitudinal edges of the envelop being bent over and forced into the bottom of the groove to form a lock, the concave portions of the envelop between the lock and the ridges preventing release of the lock.

5. A curtain-pole having a longitudina groove in its top, a pulley-plate attached to the end of the pole and having pulley-supporting ears, one or more pulleys, a fixed socket member having a segmental flange to embrace a portion of the pole, a cooperating annular member surrounding the pole, and a locking device to connect said members when the pole is in place, the pulley-plate being concealed by said members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES W. LESLIE.
